I followed up in R-sig-mac, and it turns out the reason you didn't get a 
message is that you didn't specify the package type, and the default is 
to assume you have a binary package.  A binary install just copies the 
files into place without looking at them.  If you had specified 
type="source" in the install.packages() call, you would get the same 
error messages as I got.
